Bayerisch Eisenstein DEM-GIS
Configuration-driven local GIS pipeline for a cross-border elevation model from Bavarian DGM and Czech DMR data.
Problem
Initial situation
Official elevation data, different coordinate systems and supplementary vector data must be combined reproducibly into terrain data suitable for analysis and mapping.
Constraints
Boundary conditions
- Local raw and result data
- Heterogeneous GeoTIFF and optional LAZ inputs
- Explicit target CRS EPSG:25833
- Fail-fast pipeline
- Verifiable QA
- License review before publication
Solution
Solution
A stepwise Python/GDAL pipeline checks the environment, creates an area of interest, reprojects and merges DEM tiles, derives hillshade and contours, adds vector layers and renders defined outputs.
Architecture
Architecture
- Python orchestration
- GDAL and optional PDAL
- YAML configuration
- GeoTIFF and GeoPackage
- Optional PyQGIS export
- Static SVG viewer and QA reports
Result
Result
A harmonized, cropped DEM for Bayerisch Eisenstein with terrain derivatives, PNG/PDF/SVG maps, optional QGIS project, static viewer and laser-ready elevation layers.
